Crucial M550 256GB mSATA 6Gb/s Solid State Drive

The Crucial CT256M550SSD3 is a 256GB solid state drive that uses the mSATA interface to give laptops, ultrabooks, and other space-constrained systems a quick and efficient path to flash storage.

Through a SATA 6Gb/s connection, the drive reaches sequential read speeds up to 550 MB/s and writes up to 500 MB/s, while random performance climbs to 90,000 IOPS on reads and 80,000 IOPS on writes. In everyday use that means faster boot times, near-instant application launches, and smooth multitasking even under heavy workloads.

The mSATA form factor lets the drive fit easily into slim notebooks, two in one systems, mini-PCs, and embedded projects where full-size drives will not fit. Its low power draw can extend battery life, an advantage for students, travelers, and mobile professionals who spend long stretches away from a power outlet.

Security is handled at the hardware level with 256-bit AES encryption that meets TCG Opal 2.0 and IEEE-1667 standards and supports Microsoft eDrive. These features allow businesses and individuals to enable full-disk protection without third-party software and keep sensitive data safer from unauthorized access.

Reliability matches the performance. The drive carries a 1.5 million-hour mean time to failure rating and an endurance specification of up to 72 terabytes total bytes written. That durability makes it suitable for daily productivity systems, constantly running workstations, and industrial or point-of-sale setups that demand consistent uptime.

Whether you are revitalizing an aging notebook, building a silent media center, or deploying a compact industrial PC, the Crucial CT256M550SSD3 provides the speed, security, and long-term dependability required for modern computing tasks.
